    ______________________________________________________________________________

    1) Problem Description and Brief Discussion

       Mozilla Firefox was updated to version 2.0.0.15, fixing various bugs
       including following security bugs.

       CVE-2008-2798 CVE-2008-2799 MFSA 2008-21:
       Mozilla developers identified and fixed several stability bugs in the
       browser engine used in Firefox and other Mozilla-based products. Some
       of these crashes showed evidence of memory corruption under certain
       circumstances and we presume that with enough effort at least some
       of these could be exploited to run arbitrary code.

       CVE-2008-2800 MFSA 2008-22:
       Mozilla contributor moz_bug_r_a4 submitted a set of vulnerabilities
       which allow scripts from one document to be executed in the context
       of a different document. These vulnerabilities could be used by an
       attacker to violate the same-origin policy and perform an XSS attack.

       CVE-2008-2801 MFSA 2008-23:
       Security researcher Collin Jackson reported a series of vulnerabilities
       which allow JavaScript to be injected into signed JARs and executed
       under the context of the JAR's signer. This could allow an attacker
       to run JavaScript in a victim's browser with the privileges of a
       different website, provided the attacker possesses a JAR signed by
       the other website.

       CVE-2008-2802 MFSA 2008-24:
       Mozilla contributor moz_bug_r_a4 reported a vulnerability that
       allowed non-privileged XUL documents to load chrome scripts from
       the fastload file.  This could allow an attacker to run arbitrary
       JavaScript code with chrome privileges.

       CVE-2008-2803 MFSA 2008-25:
       Mozilla contributor moz_bug_r_a4 reported a vulnerability which allows
       arbitrary JavaScript to be executed with chrome privileges. The
       privilege escalation was possible because JavaScript loaded via
       mozIJSSubScriptLoader.loadSubScript() was not using XPCNativeWrappers
       when accessing content. This could allow an attacker to overwrite
       trusted objects with arbitrary code which would be executed with
       chrome privileges when the trusted objects were called by the browser.

       CVE-2008-2805 MFSA 2008-27:
       Opera developer Claudio Santambrogio reported a vulnerability which
       allows malicious content to force the browser into uploading local
       files to the remote server. This could be used by an attacker to
       steal arbitrary files from a victim's computer.

       CVE-2008-2806 MFSA 2008-28:
       Security researcher Gregory Fleischer reported a vulnerability
       in the way Mozilla indicates the origin of a document to the Java
       plugin. This vulnerability could allow a malicious Java applet to
       bypass the same-origin policy and create arbitrary socket connections
       to other domains.

       CVE-2008-2807 MFSA 2008-29:
       Mozilla developer Daniel Glazman demonstrated that an improperly
       encoded .properties file in an add-on can result in uninitialized
       memory being used.  This could potentially result in small chunks of
       data from other programs being exposed in the browser.

       CVE-2008-2808 MFSA 2008-30:
       Mozilla contributor Masahiro Yamada reported that file URLs in
       directory listings were not being HTML escaped properly when the
       filenames contained particular characters. This resulted in files
       from directory listings being opened in unintended ways or files not
       being able to be opened by the browser altogether.

       CVE-2008-2809 MFSA 2008-31:
       Mozilla developer John G. Myers reported a weakness in the trust
       model used by Mozilla regarding alternate names on self-signed
       certificates. A user could be prompted to accept a self-signed
       certificate from a website which includes alt-name entries. If
       the user accepted the certificate, they would also extend trust to
       any alternate domains listed in the certificate, despite not being
       prompted about the additional domains. This technique could be used
       by an attacker to impersonate another server.

       CVE-2008-2810 MFSA 2008-32:
       Mozilla community member Geoff reported a vulnerability in the way
       Mozilla opens URL files sent directly to the browser. He demonstrated
       that such files were opened with local file privileges, giving the
       remote content access to read from the local filesystem. If a user
       opened a bookmark to a malicious page in this manner, the page could
       potentially read from other local files on the user's computer.

       CVE-2008-2811 MFSA 2008-33:
       Security research firm Astabis, via the iSIGHT Partners GVP Program,
       reported a vulnerability in Mozilla's block reflow code. This
       vulnerability could be used by an attacker to crash the browser and
       run arbitrary code on the victim's computer.

    2) Solution or Work-Around

       There is no known workaround, please install the update packages.

    3) Special Instructions and Notes

       Please close and restart all running instances of Firefox after the update.

    4) Package Location and Checksums

       The preferred method for installing security updates is to use the YaST
       Online Update (YOU) tool. YOU detects which updates are required and
       automatically performs the necessary steps to verify and install them.
       Alternatively, download the update packages for your distribution manually
       and verify their integrity by the methods listed in Section 6 of this
       announcement. Then install the packages using the command

         rpm -Fhv <file.rpm>

       to apply the update, replacing <file.rpm> with the filename of the
       downloaded RPM package.

    6) Authenticity Verification and Additional Information

      - Announcement authenticity verification:

        SUSE security announcements are published via mailing lists and on Web
        sites. The authenticity and integrity of a SUSE security announcement is
        guaranteed by a cryptographic signature in each announcement. All SUSE
        security announcements are published with a valid signature.

        To verify the signature of the announcement, save it as text into a file
        and run the command

          gpg --verify <file>

        replacing <file> with the name of the file where you saved the
        announcement. The output for a valid signature looks like:

          gpg: Signature made <DATE> using RSA key ID 3D25D3D9
          gpg: Good signature from "SuSE Security Team <security@suse.de>"

        where <DATE> is replaced by the date the document was signed.

        If the security team's key is not contained in your key ring, you can
        import it from the first installation CD. To import the key, use the
        command

          gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc

      - Package authenticity verification:

        SUSE update packages are available on many mirror FTP servers all over the
        world. While this service is considered valuable and important to the free
        and open source software community, the authenticity and the integrity of
        a package needs to be verified to ensure that it has not been tampered
        with.

        The internal rpm package signatures provide an easy way to verify the
        authenticity of an RPM package. Use the command

         rpm -v --checksig <file.rpm>

        to verify the signature of the package, replacing <file.rpm> with the
        filename of the RPM package downloaded. The package is unmodified if it
        contains a valid signature from build@suse.de with the key ID 9C800ACA.

        This key is automatically imported into the RPM database (on
        RPMv4-based distributions) and the gpg key ring of 'root' during
        installation. You can also find it on the first installation CD and at
        the end of this announcement.
